Exactly as in the screenshots a few posts above.
I could not get WL7 to remember any of the saved window setups. Then all of a sudden it started doing it. If I would close WL7 after I had saved the setup it would default to the factory setup when I reopened the program. This went on for over a week and then one day it suddenly started remembering the last let up I used. I too think their is a bug somewhere.
